A cabin purification system for a vehicle includes an air inlet in communication with a fan, a light source emitting ultraviolet C light at a wavelength of from 100 nanometers to 280 nanometers, a photocatalytic oxidizer element, and an air outlet. The photocatalytic oxidizer element has a surface coating comprising anatase and rutile forms of TiO2. The surface coating is illuminated by the light source. The fan generates an air flow from outside the air inlet to the air outlet. The air flow passes the light source and the photocatalytic oxidizer where the surface coating converts H2O O3 and O2 in the air flow into H2O2 which is distributed into the vehicle cabin to purify it.
